Check with Diamond I had them change the pin height
on my pistons($35) and had them open the intake valve
relief ($8) to fit my 2.08 intakes on my W-5s... so
for a added total of $43 I got what I needed

$8.00 dollars to open the intake valve reliefs on all 8 pistons? so 1.00 dollar a piece?
That is correct

My W5's are small chamber heads cut .050 for a 47cc chamber. I used a flat top piston .011 out of the hole with a .038 head gasket, worked out to like 12.7 IIRC. I guess that doesn't really help you but you can get away with as little as .027 piston to head clearance. My engine has beed 7500 many times with no problems.

Yeah, I think there was about 7cc of valve relief, it's .020 over with a stock stroke. I think if you crunch the numbers that's what it comes out to.

I'm at work and can't get on hardly any sites or I would have crunched the numbers myself, why this site is allowed I don't know.
I think I used the formula in the NHRA rulebook when I figured it. Gasket bore of 4.08 I think. I'll have to check again to be sure.

Maybe it was 10 cc of valve relief, it's been 10 years since I built it so off the top of my head I don't remember exactly.

Are you sure about the small chamber w5s ? If they are like in the 60s range the math works 
Yeah I'm sure on that, they were like 55cc uncut and the head porter milled .050 off them to get 47cc.
